I finally completed migrating the weather sensors for the weather station that is at my father-in-law’s farm. I had issues with the rain gauge not working too well with the pi directly, so I decided to use an Adafruit Trinket to capture the values of the sensors and send them to the pi for tracking. The communication between the two is accomplished using I2C.

Here’s the completed mast with sensors attached. (This is actually a pic of it at my house for testing) What you’ll need for this is 1 of each of an anemometer, wind vane & rain gauge. It works with the sensors I built, but I’m sure you could incorporate it to use any sensors you have as well….
